Hi Andy,
There are very few posts here in Spanish and certainly not enough to bug anyone. Most of these guys read and understand English very well and come here because there is far more info available here at cnczone than any other site in any other language. They post in Spanish because it's much easier and faster for them, in the same way that it is much easier and faster for me to write in my mother tongue (English) than in Spanish.
cheers
Phil
